Sixty days feeding experiment was conducted on grass carp fry fed isocaloric diets with variable protein levels in order to evaluate its growth response. Different diet ingredients were analyzed for % age protein, % age fat, % age ash, % fiber, % age moisture contents and energy. Five isoenergetic (17.91 ± 0.02 Kg MJ ) and isolipidic (8.56 ± 0.09 g) diets with varying protein levels PL1 (20%), ...

A 2 X 2 factorial arrangement with two genotypes of pigs (genetically obese and lean) and two dietary treatments (basal, a 16% protein corn-soybean meal standard grower diet, and basal +220 ppm thyroprotein as iodinated casein) was used. The 28 gilts were housed individually and fed ad libitum from 121 d of age until slaughtered at 99 kg body weight. Compared with lean pigs, genetically obese p...

in this study, the effect of maternal additive genetic and environment on body weight at 6 weeks (bwt6w), breast width (hbrs), carcass weight (carcwt), breast weight (brswt), blood hematocrit value (hem), residual feed intake (rfi), daily feed intake (dfi) and average daily gain (adg) were investigated in a commercial broiler dam line. with and without maternal effects, six different animal mod...

A 49-d feeding trial, using 192 growingfinishing pigs (avg initial wt, 32 kg), was conducted to identify pigs of widely differing average daily gains (ADG) when fed 16% crude protein diets containing either 0, 7.5 or 15% corn cobs. There were linear decreases in both ADG (P<.01) and gain/feed (P<.001) with increasing levels of dietary corn cobs. Average daily feed intake increased linearly (P<....

Thirty-six Merino lambs (8 to 9 wk of age, and 15.3 ± 0.13 kg of initial BW) 1 were used to evaluate the effects of the inclusion of 120 g sugar beet pulp (replacing 2 barley) and of the addition of 20 g sodium bicarbonate per kg concentrate on feed 3 intake, digestibility, animal performance and carcass characteristics in fattening lambs. 4 Animals were housed individually and fed barley straw...
